Embodiment Construction

[0036] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0037] FIG. 6 is a block diagram schematically showing a digital broadcast transmission system according to the present invention. 6, the digital broadcast transmission system includes a scrambler 100, a forward error correction (FEC) unit 110, a multiplexer (MUX) 120, a pilot insertion unit 130, an area determination unit 141, and a modulation unit 143 , a modulation information generating unit 145 and a radio frequency (RF) converter 150. The FEC unit 110 includes a Reed-Solomon (RS) encoder 111 , an interleaver 113 and a trellis encoder 115 .

[0038] During synchronous data transmission, the scrambler 100 performs random operations on transmitted data signals in order to prevent problems such as loss of synchronous signals due to repeated numbers such as 00000000b or 11111111b during synchronous data transmission. The scrambler 100...

Abstract

A single carrier transmitting system and a method thereof are provided. The system comprises: a scrambling code unit for scrambling a transmitted TS; an FEC unit for performing forward error correction on the scrambled TS to form a coded TS; a modulating information generation unit for generating modulating information; a multiplexer unit which receives the coded TS, segment synchronization information, bit segment synchronization information and the modulating information, and inserts the segment synchronization information and / or bit segment synchronization information and the modulating information to a starting position of the coded TS based on a control signal to form a multiplex TS containing a frame synchronization region and a data region; a radio frequency converter for performing radio frequency conversion on the modulated TS. The single carrier transmitting system is capable of reducing distortion of transmission signals in a channel environment where a burst noise exists, and improving the receipt efficiency of a receiver.

Description

[0001] This application is a divisional application of an invention patent application with a filing date of September 30, 2003, an application number of 03139100.1, and an invention title of "Single Carrier Transmission System and Method Capable of Reducing Signal Distortion". technical field [0002] The present invention generally relates to a single-carrier transmission system and method thereof, and in particular to a single-carrier transmission system and method thereof capable of improving the reliability of transmitted signals. Background technique [0003] In the era of communication multimedia, computers and broadcasting, countries all over the world have been digitizing analog type broadcasting. Especially in developed countries such as the United States, Europe, and Japan, digital broadcasting systems using satellites have been developed and put into practical use. With rapid development, different standards for digital broadcasting are respectively proposed in v...
